On the morning of August 15, in Huangling Mining Shuanglong Coal Industry West Industrial Plaza Area belonging to Shaanxi Coal Group, with the attention of all present, Shaanxi Coal Group's first set of high-efficiency intelligent complete sets of equipment for very thin coal seams in the safe operation of the staff, the successful completion of the joint commissioning, marking the first set of high-efficiency intelligent mining equipment for very thin seams of the Shaanxi-Coal Group in the success of the landing of the Yellowstone Mining Industry.

All along, the very thin coal seam intelligent mining is plagued by coal mine resources efficient mining important factors, Huangling Mining belongs to the Shuanglong Coal Industry service life has been up to 32 years, medium-thickness coal seam reserves are reduced year by year, for the mine's sustained and healthy development of the serious challenge. In the face of the plight, Huangling Mining Shuanglong coal industry as a pilot, through the regional coal seam survey shows that 0.8 ~ 1.3 meters of coal seam rich in endowment, through the realization of the very thin coal seam intelligent mining can greatly improve the resource recovery rate, extend the service life of the mine, break through the sustainable development of the enterprise's “bottleneck”.

“Intelligent mining of very thin coal seams has extremely high requirements for equipment, and at present there are very few successful cases in the industry to realize the mining height below 0.78, coupled with the complex geological conditions and other factors, which bring certain challenges to the research and development of equipment.” Zhong Zhaohai, manager of Shuanglong Coal Industry of Shaanxi Coal Huangling Mining, said.

In order to successfully nibble down this piece of impact on the high-quality development of the mine's “hard bones”, to ensure the sustainable and healthy development of the mine, Huangling Mining has organized the relevant technical personnel to go out several times to learn from the standard, the field study of intelligent mining technology in the domestic application of the thin coal seam, the success of the experience gained as an important basis for the research and development of equipment, combined with the geological conditions of the Shuanglong Combined with the geological conditions of Shuanglong Coal Industry, a clear idea of equipment research and development was clarified. And with Xi'an Heavy Equipment, Shaanxi Zhiyin a number of scientific research units in-depth exchanges, invited technical personnel in the mine field research, to determine the equipment of the system of research and development parameters, specifications, standards, etc., and successfully determine the technical program, in the joint efforts of all parties, after more than ten months of intense research and development and manufacturing, the first set of very thin coal seam efficient intelligent mining system in the mine successfully landed and debugging success.

“This system has the characteristics of high efficiency, low cost, easy maintenance and easy operation, etc. After successful application, it can not only reduce the labor intensity, but also improve the work efficiency, ensure the quality of coal, etc., and can realize the intelligent mining of very thin coal seams.” Shaanxi Coal Huangling Mining Shuanglong Coal Industry deputy chief engineer Liu Dawei said.

It is understood that this set of equipment is mainly composed of intelligent coal mining transfer system, electro-hydraulic control system and 5G leakage cable technology. With advanced technology, reliable operation, easy maintenance and repair, high production efficiency, etc., in the practical application, the lowest mining height can be reduced to 0.78m, coal mining machine, electro-hydraulic control, video system are open 5G interface communication, the use of network high-efficiency communication, to achieve the intelligent control of mining standards.

The successful application of this set of equipment can effectively reduce the labor intensity of employees, improve the operating environment, improve the level of safety management, increase economic benefits, and play an important role in cost reduction and efficiency, reduce the number of people to improve efficiency, fill the Group in the very thin coal seam intelligent mining technology gaps, for the Group in the promotion and application of the technology to provide key data, and vigorously promote the industry's pace of development of the field of very thin coal seam mining.
